Predictive Quality of Service (PQoS)

Speaker: Mate Boban, Huawei Technologies

Abstract: Predictive Quality of Service (PQoS) aims at predicting the behavior of the network at short (milliseconds, seconds) or long (minutes) time frame in advance, in order to enable proactive adaptation of the applications running over the network. PQoS includes techniques that predict the behavior of one or more key components of the network: channel, medium access, scheduling, and/or higher layer aspects. This talk will describe the application of PQoS to enable automated driving. In particular, representative current and future use cases will be discussed that benefit from PQoS and create challenges for both radio and core network design. Then, initial results of predicting uplink throughput for vehicle-to-infrastructure links based on measurement campaign will be discussed. Through both the use cases and initial experimental results, the talk will argue for PQoS as a powerful technology that can be a game changer for automated driving systems.

Evolving Autonomous Networks

Speaker: Laurent Ciavaglia, Rakuten Mobile

Abstract: The Rakuten Mobile Innovation Studio’s ultimate research goal is to devise an “artificial engineer” that has the capability to problem-solve with minimal to no human intervention – in today’s networks and future networks. To realize this goal, we are developing a novel architecture framework for autonomous networks based on population-based artificial intelligence techniques, namely, evolutionary computing. This framework is rooted in three main functional building blocks: create, validate, and apply. Create is the generation of new logic through composition or adaptation of software closed loops. Validate is the experimentation of software closed loops to network operations. Apply is the application of software closed loops to network operations. This architecture framework provides networks with the ability to go beyond their pre-defined program and learn on their own. Learning, in this sense, must be wider in scope and more powerful in execution than what is currently being deployed in networks. Indeed, this ambitious framework cannot be achieved in isolation. We are actively driving (pre-)standardization activities and are engaging in collaborative research. An overview of the autonomous networks standardization landscape will be discussed, highlighting activities from organizations such as the ITU-T, IRTF & IETF, TMF, and ETSI.

AI4SEC - Tackling Cybersecurity through AI/ML

Speaker: Pedro Casas, AIT Austrian Institute of Technology

Abstract: We are losing the battle against cybercrime. If cybercrime would be measured as a country, in 2021 it would be the third largest economy behind US and China, and cybercrime could cost more than 10 trillion USD by 2025. The cyberattack surface growth is outpacing humans’ ability to secure it. The impressive success of Artificial Intelligence (AI) and Machine Learning (ML) in multiple data-driven problems over the past decade has motivated a flourishing research domain targeting the application of AI/ML to cybersecurity problems - AI4SEC. However, making of AI4SEC an accepted and fruitful approach to cybersecurity in the practice is challenging. In this presentation, I elaborate on the most important technical show-stoppers in AI4SEC, presenting an overview on the work we have been developing over the last decade on the application of AI/ML to network security to improve the state of affairs in cybersecurity. The goal of the talk is to motivate – for the newcomers – and to strengthen – for those already in the field – the research in AI4SEC.

Tutorial "Multiverse and Adress Space Views"

Speaker: Christian Dietrich, Hamburg University of Technology

Abstract: Many software projects allow us to dynamically configure their behavior at runtime. Thereby, the use and modification of global variables is a common pattern to save or reconfigure the selected configuration. The selected configuration is then enforced by dynamically checked conditions (if statements). However, if this global configuration remains stable over long periods of time, it is questionable why one should pay the cost of constant and repeated checking. Dynamic configurability must be possible at low cost.

One approach to this problem is semi-dynamic variability. The basic idea is to let the compiler generate specialized software variants statically and to introduce them into the running program as efficiently as possible at runtime. As a concrete way to implement semi-dynamic variability, this tutorial will introduce Multiverse: Multiverse is a GCC plugin and a run-time library, which allows to specialize single C-functions for certain assignments of global variables. Through run-time binary patching, the respective specializations are anchored in the code segment without loss of efficiency.

In order to perform this run-time code patching efficiently without disturbing the normal operation of the process, we will look at address space views. Here, multiple, synchronized, ‘views’ are established on the address space within a UNIX process. While one thread prepares the code segment for a new multiverse configuration, all other threads continue to run undisturbed.

Tutorial "TSN for plug-and-play networks: How can the tools be used in practice?"

Speakers: Tobias Hoßfeld, Julius-Maximilians-Universität of Würzburg, Alexej Grigorjew, Julius-Maximilians-Universität of Würzburg

Abstract: The Time-Sensitive Networking group specifies a number of standards that define the behavior of the switch data plane, and provide interfaces for their configuration to achieve deterministic networking. Yet, the proper configuration of these tools remains an important research-topic, as it heavily depends on the aspired use case. In dynamic plug-and-play networks, real-time traffic streams can emerge and disappear at any time, and stream reservation algorithms must be able to compute the required resources in time. This tutorial explains important tools in the TSN kit for bounded latency from the perspective of industrial automation networks. It presents example algorithms for the configuration of selected mechanisms and discusses their trade-offs, as well as important relations with reliability tools to keep in mind.

List of topics:

  • What is TSN: Overview on IEEE 802.1 TSN Standards
  • Basics of bounded latency: What do we need?
  • Challenges of bounded latency computation: Stream reservation, Audio Video Bridging, and the snowball effect
  • Overview of TSN bounded latency mechanisms: What are their key properties?
  • Complementary mechanisms for redundancy and efficiency: What must be considered?
  • Brief comparison: What are the trade-offs?

Tutorial "Fyr: A Memory-Safe and Thread-Safe Systems Programming Language"

Speaker: Torben Weis, University of Duisburg-Essen

Abstract: Systems programming languages with safety guarantees like Fyr and Rust aim to replace C/C++ in domains such as operating systems and embedded systems. The promise is to deliver safety with zero overhead at runtime, because the compiler is able to sufficiently analyze the code at compile-time. However, the static code analysis required for the additional safety guarantees imposes restrictions on data structures and algorithms operating on them.

Fyr is a new open source systems programming language that uses group-based memory management to overcome some of the restrictions caused by pure ownership-based memory management as in Rust. The tutorial explains the concept of group-based memory management used by Fyr, which allows for graph-shaped data structures. In contrast, a pure ownership-based system automatically implies tree-shaped data structures, because each pointer constitutes an ownership. To overcome the remaining restrictions on data structures, Rust and Fyr feature reference counting mechanisms. However, this causes runtime overhead and evades the static code analysis of the compiler. Thus, the tutorial shows in several examples where the promise of zero overhead safety holds, and where runtime overhead is currently unavoidable.

To this end, the tutorial explains the tradeoffs and limits implied by the static code analysis required for memory and thread-safety. Furthermore, we explain the difference between ownership-based memory management as used in Rust and group-based memory management as featured by Fyr.
